AI Technical Summary

Benefits of technology

The patent text describes a confirmation screen that shows information about a change in brightness range of a display device. This information prompts the user to make the necessary changes, such as connecting the HDMI cable to a compatible HDMI terminal or adjusting the brightness range on the display device. The controller sends this information to the display device based on a correspondence between the display device and the brightness range. This confirmation screen helps users make informed decisions when making these settings changes.

Problems solved by technology

If this should happen, the problem will be that the HDR compatible video content is not properly outputted from the playback device to the display device.

first embodiment

[0026]1-1. Configuration of Playback System

[0027]First, the configuration of a playback system 2 according to a first embodiment will be described through reference to FIG. 1. FIG. 1 is a block diagram of the configuration of the playback system 2 according to the first embodiment.

[0028]As shown in FIG. 1, the playback system 2 comprises a playback device 4 and a display device 6. The playback device 4 is, for example, a digital video player for playing back video content stored on a DVD, a BD, or the like. The display device 6 is, for example, a television set for displaying the video content played back by the playback device 4.

[0029]Both the playback device 4 and the display device 6 are HDMI devices. The playback device 4 and the display device 6 are connected together via an HDMI cable 8. The HDMI cable 8 is a cable conforming to the HDMI standard, and is a cable for transmitting digital signals. The HDMI standard is a standard of a communication interface for transmitting vide...

second embodiment

[0069]2-1. Configuration of Playback System

[0070]The configuration of the playback system 2A according to a second embodiment will be described through reference to FIG. 6. FIG. 6 is a block diagram of the configuration of the playback system 2A according to the second embodiment. In FIG. 6, those components that are the same as the components in FIG. 1 of the first embodiment are numbered the same and will not be described again. This also applies to the other embodiments given below.

[0071]As shown in FIG. 6, with the playback system 2A according to the second embodiment, a storage component 22A of a server device 20A stores correspondence information. That is, unlike in the first embodiment, the correspondence information is not stored in advance in the playback device 4A.

[0072]A processor 32A of a playback device 4A generates a request signal for requesting the server device 20A to transmit the correspondence information. An acquisition component 28 and the processor 32A constitu...

third embodiment

[0080]3-1. Configuration of Playback System

[0081]The configuration of the playback system 2B according to a third embodiment will now be described through reference to FIG. 8. FIG. 8 is a block diagram of the configuration of the playback system 2B according to the third embodiment.

[0082]As shown in FIG. 8, with the playback system 2B according to the third embodiment, a communication component 26B of a playback device 4B is a CEC (Consumer Electronics Control) communication interface that exchanges CEC commands with a display device 6B. A communication component 38B of the display device 6B is also a CEC communication interface that exchanges the CEC commands with the playback device 4B.

[0083]In the HDMI standard, the CEC is defined for linking between a plurality of HDMI devices. According to the CEC, the CEC commands are bidirectionally communicated between a plurality of HDMI devices. This communication is called CEC communication.

[0084]A processor 32B of the playback device 4B ...

Abstract

A playback device is configured to be connected to a display device. The playback device includes a communication component and a controller. The communication component communicates with the display device. The controller acquires setting information indicating a current setting of a brightness range in the display device from the display device via the communication component. While a specific brightness range has not been set in the display device, the controller transmits information related to a setting change to the specific brightness range via the communication component to the display device based on correspondence information indicating a correspondence relationship between the display device and the brightness range that is settable in the display device.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Japanese Patent Application No. 2018-019058 filed on Feb. 6, 2018. The entire disclosure of Japanese Patent Application No. 2018-019058 is hereby incorporated herein by reference.BACKGROUNDField of the Invention[0002]This invention generally relates to a playback device. More specifically, the present invention relates to a playback device that is configured to be connected to a display device.Background Information[0003]Playback devices such as a DVD (Digital Versatile Disc) players or BD (Blu-ray (registered trademark)) players are known in the field of playback devices. These playback devices are connected to a display device such as a television set, for example. HDMI (High Definition Multimedia Interface (registered trademark)) is used as a communication interface for transmitting video signals and the like at high speed between the playback device and the display device. Therefore, the display dev...
